I have an 06 DC with a Borla cat back. It sounds great. You can get it with rear or side exit pipes. It uses the stock mounts. It's a bit pricey, but it's made from aircraft grade stainless steel and will last for the life of your truck. If you visit their site, they have sound files you can play if you want to listen to it. Frankly, it's a bit louder in real life than on the site. That is not a bad thing, though!
